ADJUSTABLE JOURNAL-BOX FOR. TRUCKS.

To all whom it may concern:

Be it known that I, SHERWOOD M. Cruse, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Adjustable Journal-Boxes for Trucks, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to adjustable journal boxes for trucks.

The object of the invention is to provide a journal box for use inconnection with in dustrial railway cars which will automaticallyaccommodate itself to the various positions assumed by the axle owing tothe irregularities in the track or to other causes.

To this end it is a further object of the invention to provide a journalbox movable about a horizontal axis extending at right angles to thelength of the axle and bodily movable in a substantially vertical plane.

In the accompanying drawings, Figure 1 is an elevation of a portion ofan axle, showing the same supported in a journal box embodying myinvention; Fig. 2 is a vertical, sectional view, taken centrally of theaxle shown in Fig. 1; and Fig. 3 is a side elevation, partially insection, of what is shown in Fig. 1.

In these drawings I have illustrated one embodiment of my invention andhave shown the same as applied to a truck of ordinary constructioncomprising a main frame 1 having depending bearing brackets 2, in whichare supported the bearings for the outer ends or journals 3 of an axle4, upon which are mounted track wheels In the form here shown the lowerend of the supporting bracket 2 is bifurcated and the depending arms 6thereof are provided in their adjacent faces with vertically arrangedslots or guideways 7 the upper ends of which are closed by inwardlyextending walls or lugs 8. Journal boxes 9, which may be of any suitablecharacter and are here shown as containing bearing rollers which supportthe journal 3, are provided with laterally extending trunnions 10arranged in a substantially horizontal plane and extending atsubstantially right angles to the length of the axle. The ends of thesetrunnions extend into the grooves 7 in the arms 6 of the supportingbracket and have both a pivotal movement and a vertical slid-Specification of Letters Patent.

ing movement relative to that bracket. Normally, the weight of the caris supported on the journal box through the medium of the trunnions andthe lugs 8 which close the upper ends of the slots 7 and rest upon thetrunnions. The lower ends of the slots 7 may be closed in any suitablemanner, but, in the present instance, I have secured a bar 11 to thelower ends of the arms and this bar extends across and closes the lowerends of the slots in those arms.

It will be apparent that with the journal box constructed in the mannerhere shown the wheels are free to follow any irregularities in thetrack; and that the journal box will automatically adjust itself to thevarying inclinations of the axle, thereby maintaining the journal box atall timesin true alinement with the journal and eliminating the wear andresistance incident to the binding of the journal in the journal boxwhere the latter is rigidly mounted. It will further be noted that theouter end of the journal box is provided with a loop or shield 12 whichextends beyond the end of the journal and forms a dust guard to preventdust or dirt of any character from entering the bearing. The supportingbracket 2 is also provided with an inwardly extending shield 13extending beyond the inner end of the journal box and serving to preventthe entrance of dust or dirt at that end of said journal box.

I wish it tobe understood that I do not desire to be limited to thedetails of construction shown and described, for obvious modificationswill occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. In a truck, the combination, with a main frame, an axle, and trackwheels carried by said axle, of a supporting bracket having verticalguideways therein, and a journal box having trunnions slidably andpivotally mounted in' said guideways.

2. In a truck, the combination, with a main frame, an axle, and trackwheels mounted on said axle, of a supporting bracket carried by saidmain frame and having a bifurcated lower arm, the arms of saidbifurcation having grooves in the adjacent faces thereof, and a journalbox having trunnions arranged in a substantially horizontal plane,extending transversely to the length thereof and slidably and pivotallymounted in said grooves.

8. In a truck, the combination, main frame, an axle, and track wheelsmounted on said axle, of a bearing bracket carried by said main frame, ajournal box pivotally and slidably mounted on said bearing bracket, anda dust shield carried by said bracket and extending inwardly beyond theend of said journal box.

4;. In a truck, the combination, with a main frame, an axle, and trackwheels mounted. on said axle, of a bearing bracket with a carried bysaid main frame, a journalbox pivotally and slidably mounted on saidbearing bracket, a dust shield carried by said bracket and extendinginwardly beyond the end of said journal box, and a dust shield carriedby said journal box and extending beyond the outer end thereof.

In testimony whereof, I aflix my signature in presence of two witnesses.
